Instead, the network, which includes KRMA-Channel 6 in Denver, will show “The Naked Planet,” “The Dead Sea” and “The Grand Canyon,” beginning at 9 p.m.

“I took a look at it at 10 this morning,” said James Morgese, president and general manager of RMPBS. “What I saw is nothing worse than what you see on TV elsewhere, but in this era of heightened sensitivity by the FCC, fines are pretty stiff.”

Specifically, he said, the questionable scenes were 200-year-old pencil drawings of nude couples having sex and “a very specific” discussion of Louis VXI’s apparent impotency.

“It’s a good show, historical and factual,” said Morgese, adding that the show will air at 10 p.m. on an undetermined date. “After 10 p.m. and before 6 a.m. is considered ‘safe harbor’ where you can do these things and not get into trouble.”

Some PBS outlets pulled the program entirely, others are moving to a later hour and some will show it at its schedule time. “It will be interesting to see what happens,” said Morgese.

The FCC has heavily fined some radio and television stations for language and scenes deemed to be obscene.
